Serial No. 715,110.

To'all whom/t may] concern Be it known that- I, CHARLES H. FOX, a citizen of the United States, residing at Bakersfield, in the county of Kern and State of California, have invented a new and useful Pump, of which the following is a speciication.

This invention .has 'refer-ence to improvements in pumps, and its object is to provide a means for elevating water directly by the energy developed by the burning.;l of an eX- plosive mixture especially an esplosi ve mir;- turc of a hydroiizarbrm and air.

T he present invention is designed more particularly for the elevation of water from wells to the surface and to any desired point above the surface of the ground, and to this end the invention comprises one or more erplo'sion chambers to be located at a suitable depth in the well, such depth being as clef-:e to the bottom of the well as circumstances will permit, and leading from the.

explosion chamber in coinnn'inication. therewith is a water conducting. pipe continued to the top of the ground and to any suitable point for the disposition of the elevated water. Provision is also made for introducing an explosive mixture into the explosion chamber near the bottom of the well and the ignition of such explosive mixture in a manner to cause the great volume of rases so formed to be projected into the pipi.1 provided for the outfiow of water, whereby the frases serve to lift the. water to the surface. By a suitable arrangement at the surface of the ground. the introduction of the explosive mixture into the explosion chamber or chambers and the tiring of the expl4` ye 'mixture may be controlled as may be needed.

The invention will be best understood from a consideration of the followingl detailed description, taken in connection with the accompanying drawings forming a part ot this speci cationf with the further understanding that while the drawings show practical forms of the invention, the latter is susceptible. of other practical embodiments and may, therefore, be changed and modified s-:a long-as such changes and modifications marl( no'material departure from. the salient features of the invention.

ln the drawingst---Figure l is a view showing thi` lower end of a well and illustrating an enibmliment of 'the invention.

, moving parts.

Fig. 2 is a section on the line 2-2 of Fig. l, but drawnv to a larger scale. Fig. 3 is a longitudinal diametric section of one of the explosion cylinders employed in the structure shown in Figs. 1 and 2. Fig. 4- is a vertical section through the explosion chambers of a double actingl pump structure cm.- bodying the features of Fig. l and also illustratinge means for lubricating the Fig. 5 is a vertical central section through a. portion of the explosion chamber of Fig. 4- showin the exhaust ccndut but omitting the piston from the ei;- plosion chamber. the structure shown in Fig. 5 with the ei;- plosion chamber shown in cross section ano. distant parts omitted.

Referring to the drawings, there is shown a well casing;l l. which may be taken as indicative of any suitable well assumed to be sunk to a suitable depth and to contain a body of water, although for clearness of illustration no Water'is indicated in the drawings.

Within the well casing there is located a pipe 42 which may be considered as extend.- ing to a sufficient depth below the normal surface of water contained in the well and secured to the lower end of tl i pipe 42 and grouped thereabout are cylinders 43 ,f-:hown

as four 1n number, but this particular number 1sV not obligatory. llach cylinder is provided at the ends with heads 44, 'which since the cylinders are usually placed upright may be called the upper and lower heads of these cylinr. ers. At a mid point of each cylinder there is an exhaust pipe orduct "i5 communicatingwith a common outlet 46 er tending upwardly into the pipe 42 and there freely open. Nithin each cylinder there lodged a reciprocatory member shown iu the drawings in the form of a piston l? provided with packing rings 48, and since the cylinders are designe-,d to receive plosive mixtures the piston-t7 may he in effeet similar to the pistons of ordinary plosion engines, but the pistons el? have no piston rods or pitmcn. The reciprocatru'r Fig. ,6 is a plan View of Ma: [L:

members or pistons 47 perform the functione Y of compressors and valves1 as will hereinafter appear, and are capable of moving lengthwise of the cylinders with requisite freedom, although they should fit the cylinders sufliciently tight to prevent undue leakage about them.

Leading into the well outside the pipe; 42 is a pipe 23a havingl branches 49 openmr through both the up ler and lower heads o 4 the cylinders 43. lachpipe 23 and 23 is provided with a check valve 50 designed to prevent back-liring. Each cylinder 43 has near each end a spark plug 41L fed by conductors 39a carried through pipes 40u, such conductors coming from. a source of suitable current supply' such as iscustomary to use in connection with explosion engines, there being in the structure shown in Figs.

' 3 and 4 as many pipes 40 and sets of con ductors as there are cylinders 48, this providing for the energization of the spark plugs in such order as may seein advisable.V

Each upperand lower head of each cylinder is provided with a pet cock 5Of1 under the control of a rod 51, the arrangement being such that any one or more of the pet cocks may be opened as may be desired for a pur pose which will presently appear.

Let' it be assumed that the structure,

shown is at rest, the pistons 47 will gravitate to the bottom of the cylinders. and the upper ends of the cylinders will become full of water through the exhaust passages 45. Now, by opening the upper pet cocks and forcing an explosive mixture through theA pipe 23a it will flow into the cylinders and the ends of the cylinders below the pistons will become filled with the explosive mixture, causing the pistons to rise and force the water out through the pet cocks in 'the upper headsof the cylinders. By now energizing the spark plugs in proper order explosions will occur forcing the pistons toward the ends of the cylinders remote from that in which the explosion takes place and the pet cocks being closed a cycle of operations is established, so that by causing the explosions to occur in order the pistons will reciprocate in proper relation one to the other to produce through the outlet 46 a rapid succession of forceful streams of gases which will serve to lift water within the pipe 42 to the surface of the ground, and

.these explosions may be made to follow ing the explosion chambers. In this struc,-y

ture there vis a cylinder 43 in which, a piston v478L may move freely under the action.

of the exploding gases. Atl'each end of the cylinder 43a there is al reduced extension 52 of thebore of lthe cylinder, and this'extension receives a ,cap orhea'd 53 to which is connected the inlet 49 fory the fuel.

The cap 53 carries a valve 54noi'1nally is limited by a pin 56 traversing thelstern The valve stem is carrled intola branch 57 of a T 58 located within the con- 4 duit or pipe 49 and'from the other branches of the T lead pipes 59 through the conduit 49 to respective check valves 60, 60:l Thel valve 60, opening toward the T 58 is connected to a pipe 6l leading to the surface of the ground ,and there suppliedV with an appropriate quantity of lubricant. rlhel other valve 60, opening away from the T 58 is connected to a pipe 62 ywith branches 63 tapped into the cylinder 43 in the pat-h of the piston 47, so as to feed lubricant thereto. The valvel stem 55, moving in the central branch of the T 58', acts as a ,pump for the lubricant, the' valves 60and 60a serving as pump valves. The other 'endof the cylinder may be similarly provided with a valve 54 and associated parts and connected upto the supply pipe 6l and a pipe 62 leading therefrom is connected by branches 63 to the cylinder to also supply lubricant thereto, so that thepiston 47a may receive lubricant from opposite sides. two ends of the cylinder are alike it is deemedunnecessary to illustrate the structures at more than one end of the' cylinder.

The piston in the structureshown in Fig. 4 is provided at each end with an axially extended stem 64, while in that portion of the cylinder having the reduced bore 52 thewalls are provided with a tapped pas-v sage 65 receiving a spark plug 4lb which may be similar to the spark plugs of the Since the icc i otherstructures except that in this case theI spark plug has terminals 66 so located as to be within electrical striking dist-ance of the appropriate stem 64 when the latter is vbrought into proper relation to the termi7 nais 66. By supplying the spark plu with an electric current of suiliciently h'ig ten sion sparks will pass from one terminal 66 to the stem 64 and from the llattergto the other terminal 66, thus assuring the ignition of the explosive mixture.

It is of advantage Ito avoid the entrance of water into the cylinder,'wherefore the cylinder may be provided with an outlet 45a terminating at its outer end in a valve seat 67 to which avalve 68 is adapted, this'valve being preferably conical in shape and pro,- vided with a directing stem 69 carried bye.

i,cage 70 in turn made fast to the discharge )end of the `exhaust conduit. By this meansthe exhaust conduit is closed except when, gases of explosion a e passing therethrough,

and under these ci umstances the pressure.

of these gases is too great to permit water to enter the exhaust conduit. llVhen the pressure lowers su'tiiciently to permit the entrance of vWater into the exhaust conduit `the valve (38 drops to the seat 67 and so closes the conduit against the entrance of Water. lt will be understood that Whether one or a number of cylinders are employed the exit end of theexhaust conduit is provided with a valve preventing the entrance of Water.

it will be understood, of course, that the structures of Figs. 4l, 5 and G are tobe asl sociated with thevvater pipe 42 and that vWater pipe, power.

the cylinders 47 may be multiplied'in the same manner as shown in Fig. 1.
